Subject: [PATCH 4/5] sfc: Add workspace for GMAC bug workaround to MCDI MAC_STATS buffer
|
|
|
|
Due to a hardware bug in the SFC9000 family, the firmware must
|
|
transfer raw GMAC statistics to host memory before aggregating them
|
|
into the cooked (speed-independent) MAC statistics. Extend the stats
|
|
buffer to support this.
|
|
|
|
The length of the buffer is explicit in the MAC_STATS command, so this
|
|
change is backward-compatible on both sides.
